Answer:

The length is equal to 12 and the width is equal to 6.

Step-by-step explanation:

In order to find the values here, we start by setting the width equal to x. Now knowing this, we know that the length is twice that long. Therefore, the length would be equal to 2x. Now we can use the perimeter formula to solve the equation.

2L + 2W = P

2(2x) + 2(x) = P

4x + 2x = 36

6x = 36

x = 6

Now with the given value for x, we can tell that the width is 6 and then we multiply it by 2 to get the length value (12).

Drag each figure to show if it is similar to the figure shown or why it is not similar.
schepotkina [342]

Answer:

Step-by-step explanation:

Similar figures have the same shape but the same size.

Moving from left to right:

The first figure is similar because it is rotated

The second figure is not similar because of shape

The third figure is not similar because of different ratio the ratio for the figure above is 3/5 or 0.6, while this figure is 12/15 or 0.8

The fourth figure is not similar because of ratio, but it is still a rectangle

The fifth figure is not similar because of shape

The last figure is similar because the ratio is the same with 6/10 or 0.6

Y = mx + c

If y = 4, and x = 0, then:

4 = -1 (0) + c

c = 4

If c = 4:

y = -1 (2) + 4

y = -2 +4

y = 2

If you plug in the different values of x in each equation, the answer should be:

2,0,-2
